Canon TR9050 Ink Absorber Full Reset

If your Canon TR9050 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

During head cleaning, surplus ink is routed to internal absorber pads. Canon TR9050 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon TR9050. Service mode instructions are shown only when a matching series procedure is known.

What You May Notice

• Service / maintenance warning on the screen or driver
• Printer refuses to print even with ink available
• Blinking lights and queued jobs fail
• Error reappears after restart

How to Enter Service Mode on Canon TR9050

Some Canon series require entering service mode before the ink absorber counter can be reset.

1. Turn the printer OFF.
2. Press and hold Stop/Reset.
3. While holding Stop/Reset, press and hold Power.
4. Release Stop/Reset (keep holding Power).
5. Press Stop/Reset 5 times.
6. Release Power — the printer should enter service mode.

If it doesn’t work, repeat the sequence carefully. The press count depends on the series.

Clear the Ink Absorber / Waste Ink Counter

Once the counter is cleared, Canon TR9050 should exit the locked state and printing should resume normally.

Important Notes

If absorber pads are truly saturated, ignoring maintenance can lead to ink leakage inside the printer. The counter reset only removes the software lock.
